Application led January 30, 1928. Serial No. 250,372.

My present invention relates to improve- 'ments in hygiene heating and cooling systems adapted for use in rivate and public buildings, by means of w ich fresh air may be supplied at all times to the interior of the building and the air may -be warmed 1n cold weather or the temperature of the atmosphere in the house may be reduced 1n summer, by the circulation of air currents 10 to eject warm air or to introduce cooler air means are utilized for removing excessmoisture from the air before it passes to the heating furnace.

In the accompanying drawings, Iy have illustrated one complete example of the physical embodiment of my invention in which alternate structures are employed in the Ventilating system and in which the parts are combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

Y Figure 1 is a perspective view showing the Ventilating system and disclosing two floors of a house that is equipped with the heating System;

Fig. 2 is a detail longitudinal, vertical,

adjacent parts of the heating system as at line 2-2 of Fig.' 3;

Fig. 4 is a perspective view showing the cold air flue partly broken away to disclose the air washing and air drying screens within the flue;

Fig. 5 is a transverse or horizontal 'sectional View of the hot air flue at line 5-5 ofv Fiv. 1;

Fig. 6 is a perspective view showing one of the distributing heads connected. with the branch hot air Hnos; and

Fig. 7 is a. detail view showing the manner of venting the smoke stack of the furnace or other flues built to carry off the cold air from the room being heated.

In the drawings in which the preferred embodiment of my invention is illustrated, I utilize a well known type of steam boiler 1 having the usual grate 2 and the combustion chamber 3 and above the combustion chamber are arranged the fire tubes 4 through which the smoke or gases of combustion pass from the rear of the furnace to the smoke chamber 5 in the front of the furnace. The smoke as usual passes from the smoke chamber up through the smoke pipe 6. The lire tubes are enclosed'within a horizontally disposed cylindrical-drum 7 and in the upper portion of this drum 7 are arranged horizontal air tubes or flues 8 which are air heating tubes and through which the air to be heated passes fromthe open rear end of the drum to the front of the drum and thence these heated air currents pass upwardly through the hot air tube 9 in the top of the drum and thence to the main hot air flue 10 which rises vertically from the drum and extends to the topmost floor of the building to be heated.` On each of the floors, the main hot air flue is provided with laterals 11 which may be located at the ceiling or along the floor of the rooms and these laterals are fashioned with discharge heads or distributing heads which comprise a plurality of nozzles 12 through which the hot air is distributed to the room. A damper 13 is provided in each lateral 11 so that the passage of hot air currents through the distributing heads may be manually controlled in usual manner.

In order to prevent loss of heat by radiation from the main hot air flue 10, I pro vide a jacket 14 which forms a vacuum space 15 about the exterior of. the main hot air flue, and a suction pipe 16-from this vacuum space extends to a vacuum pump 17 which is located in the basement or cellar of the 100 building to be heated adjacent to the furnace. When the vacuum is in operation, air is drawn from the vacuum space 15 and therefore loss of heat by radiation from the main hot air flue 10 is revented.

At the rear of the urnace, an air inletV chamber 18 is provided within the furnace walls ,and a partition 19 is extended from the rear wall of the furnace to the drum to complete this enclosure. A cold air port 20 110 is provided in the rear wall ofthe furnace and communicates with the air chamber 18 and a cold air gate 2l is hinged at 22 and provided with a crank handle 23. The crank handle is accessible from the exterior of the furnace and this gate 2l may be turned upwardly to horizontal position as in Figs. 2 and 4: to permit passage of air currents through the port 20 to the chamber 18 and thence to the heat-ing pipes or tubes 8. The cold fresh air is .supplied to the furnace at the cold air port 20 from the coldv air Hue 24, and a fau blower 25 is used to create a forced draft of air through the cold air Hue. The fan blower has an intake pipe 26 and a hinged door 2T to regulate the quantity of air supplied -to the pipe, and the discharge pipe 28 of the fan blower is connected with the cold air Hue 24.

lVithiu the cold air Hue, I provide a reticulated screen or washer 29 over which water is designed to How from the water pipe 30 and it Will be apparent as the water slowly trickles or Hows over this reticulated washer, the moisture and screen will wash the air currents passing therethrough, and the excess water passes 0H' through the drain pipe 31 belo'w the cold air Hue. In order to remove the excess moisture from the washed o'r purified air, a second reticulatedscreen 32 is transversely disposed in the cold air Hue'and the presence of this screen or drier causes the removal of excess moisture from the air currents passing through the reticulated screen. It will be understood that the cold air is drawn into the Ventilating system by means of the fan blower and the air currents are forced through the heating tubes 8 and then the hot air currents pass upwardly through the main hot air Hue and are distributed by means of the nozzles in i the heads of the laterals.

In some instances, it is desirable to use natural draft instead of forced draft for supplying the air to the furnace and for this purpose, as shown in Fig. 3, I utilize side plates 33 Within the furnace walls and connected with the exterior of 'the drum 7. These side 'plates form side Hues 34 which communicate with ports 35 in the side walls of the furnace and doors or gates 36 regulate and control the passage of cold air through these ports to the side Hues 34. As the natural air currents moving upwardly pass over the top of the drum to vthe main hot air Hue 10 the air currents are heated and are then distributed as usual.

When it is desired to introduce fresh air through the Ventilating system without heating the air, as in `summer time, the gate 21 is turned to vertical position to close the top of the furnace to the main hot air'Hue 10. As thus arranged, the fan blower may be utilized to supply washed, moistened, and

purified cool air currents to the interior ofv the house.

In Figs. I and 7, I illustrate a cold air port 38 in the smoke vpipe by means of which cold air currents may be transferred from the Hoor portion of the room to the interior of the smoke pipeor air'Hues built for that purpose, and within the smoke pipe a deHector plate 39 is provided to guide the cold air currents and to prevent egress of smoke from the smoke stack. warm air currents are supplied to the upper portion. of the room, thev cold air currents are allowed to pass through the port 38 thus insuring a'complete circulation of air in the dwelling with a continuous ventilation to insure fresh airat all times. i

Having thus fully described my invention, what I claim as new and desireto -secure by Letters Patent isl. The combination with a hot air heating furnace having a main hot air Hue, and a cold -air Hue with an inlet port to the furnace,

and a fan blower connected with said cold air Hue, of means in the Hue for wet-washing the air currents and means for subsequently extracting moisture from the Washed air currents, laterals connected to the main hot air Hue, and 'discharge heads connected to said laterals. l

2. The combination with a hot air heating furnace having a hot air Hue and meansfor distributing hot air currents, of a rjacket around the hot air Hue and means for causing a vacuum'in the jacket, a cold air Hue connected with they furnace` and means for passing air currents through said cold air Hue, wet-Washing means within the cold airA Hue, and means Within the cold air Hue for subsequently eliminating excess moisture from the washed air currents.

3. The combination with a hot air heating furnace having a cold air Hue with its port in the rear wall ofthe furnace and a cold air chamber between the furnace and said port, of a main hot air Hue from the front of the furnace, meansfor supplying air under pressure through the cold air Hue, an exterior cold air pipe from the port to the main hot air Hue above the furnace, and a hinged.

gate, for alternating How of air from the port to the furnace or to said cold air pipe. In testimony whereof I aHix my signature.
